摘要
本文选用五种不同的激发剂,在相同的条件下激发再生微粉的活性,以砂浆的抗压强度、孔隙率、平均孔径、SEM为指标,根据指标判断五种激发剂激发再生微粉的效果,实验结果表明:CaCl_2激发再生微粉效果最好,CaSO_4·2H_2O激发效果次之,NaOH、Ca(OH)_2、Na_2SO_4激发效果稍差,但其再生微粉活性激发的效果都好于无激发剂作用的对比试样。
In the experiment of the paper, five different activators were chosen to activate the building debris and their activating effects are quantified by five indexes, i.e. compressive strength, porosity, average pore diameter and SEM of the mortar made with the activators under the same condition. The experiment results explain that CaCl2 is the most effective to activate the recycled building debris, and CaSO4 · 2H2O is the second effective. NaOH, Ca（OH）2, and NaRSO4 are the poorest, but the mortar activated with them has better indexes than that without activators.
